Conjugate Acid - Base Pair - An acid after losing a proton becomes a base whereas a base after accepting the proton becomes an acid. For example, let us consider the reaction between water and ammonia as represented by ..

An acid after losing a proton becomes a base whereas a base after accepting the proton becomes an acid. For example, let us consider the reaction between water and ammonia as represented by the following equilibrium: In the forward reactio..

When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a hydrogen ion, it is in fact giving away a proto..

Lewis Concept of Acids and Bases - Although Bronsted-Lowry theory was more general than Arrhenius' theory of acids and bases, it failed to explain the acid-base reactions which do not involve transfer of proton. For e.g., it fails to expla..

Although Bronsted-Lowry theory was more general than Arrhenius' theory of acids and bases, it failed to explain the acid-base reactions which do not involve transfer of proton. For e.g., it fails to explain how acidic oxide such as anhydrous C..

According to Bronsted-Lowry theory, an acid is a proton donor and base is a proton acceptor. Therefore the strength of an acid or a base is determined by its tendency to lose or gain protons. A strong acid is a substan..

In 1923, J.N.Bronsted and T.M.Lowry proposed a more general theory known as the Bronsted-Lowry proton transfer theory. According to this concept, any hydrogen containing species (a molecule, a cation or an anion), which is capable of donating one or more protons to any other sub..

>Strength of a base depends on the concentration of hydroxyl ions. A strong base dissociates completely in water. Example: Sodium hydroxide A weak base dissociates partially in water. Example: Ammonium hydroxide The acidity of a base is equal to the..

Physical Properties of Amino acids - Amino acids are colourless, crystalline solids. They are water-soluble high melting solids and behave like salts. The a -carbon atom has 'R' which is a side chain. This side chain is different for different amino acids. The carboxyl..
